PIPE-FLANGING TOOL.

Specification of Letters Patent.

Patented Aug. 24, 1920.

Application filed October 17, 1919. Serial No. 331,280.

To all whom it may concern Be it known that 1, JOHN F. WALTERS, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Pipe- -Flanging Tools, of which the following is a specification.

The invention relates to a tube fianging implement, and more particularly to the class of flanging pliers for copper tubing.

The primary object of the invention is the provision of an implement or pliers of this character, wherein the fianging of the end of a copper tubing ordinarily used as an oil, air' and gasolene feed pipe, can be readily effected, without necessitating the removal of the tubing in its installation in an automobile or other place of usage, the implement or pliers being of novel construction whereby different sizes of flanges can be made thereby in the use of the same.

Another object of the invention is the pro vision of an implement or pliers of this character, wherein different sizes of flanging'plungers can be fitted therein and the same eccentrically adjusted to bring it in alinement with the longitudinal axis of the end of the tubing to be flanged, the plunger being self adjustable in the use of the tool.

A further object of the invention is the provision of an implement or pliers of this character, wherein the tubing to be flanged can be readily clamped at its end so that the flanging plunger will become active on manipulation of the implement or pliers thereon for the flanging of the tubing with despatch and without requiring excessive leverage on the part of the user of the implement or pliers.

A still further object of the invention is the provision of an implement or pliers of this character, which is extremely simple in construction, thoroughly reliable and efficient in operation, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts, as will be hereinafter fully described,

illustrated in the accompanying drawings,

and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a perspective view of the implement or pliers constructed in accordance with the invention, showing the tubing clamp -1n open position and the end of a tubing therein.

Fig. 2 is a view similar to Fig. 1 showing the tubing clamp closed and the Hanging plunger engaged with the tubing end for the flanging thereof.

Fig. 3 is a fragmentary vertical sectional v1ew showing in detail the eccentric flanging plunger mounted in one of the levers of the implement or pliers.

Fig. & is a fragmentary vertical longitud nal sectional view showing in detail the p1vot oints.

Similar reference characters indicate corresponding parts throughout the several views in the drawings,

Referring to the drawings in detail the implement or pliers comprises a pair of levers 5 and 6 respectively, each being formed with a handle end 7, which may be of any required length, while the opposite end portion is flat faced as at 8. The lever 5 at the fiat faced end portion 8 thereof is formed with a bifurcated extremity pro viding spaced parallel pivot ears 9, while the corresponding end portion of the other lever 6 is longitudinally divided to form companion tube end clamping jaws 10 and 11- respectively.

The clamping jaws 10 and 11 at their outer ends are overlapped to receive a pivot pin 12 for swingingly connecting said jaws together and this pin 12 is formed with an eye head 13 which is received between the pivot ears 9 on the lever 5 and passed through these ears 9 and said eye 13 is a pivot 14 for swingingly connecting the levers 5 and 6 together.

In the inner faces of the jaws 10 and 11 are formed registering notches 15 constituting companion seats for tubing ends 16, the companion seats formed by the notches 15 varying in sizes so as to receive different sizes of tubing to be flanged at their ends. Swiveled or otherwise engaged in the jaw 11 is a bolt 17 which is adapted for threaded engagemerit in the jaw 10 so that on the closing of the jaw 11 relative to said jaw 10 the tubing end 16 can be securely clamped therebetween and held in the companion seats 15 in the inner faces of said aws for the flanging of the tubing 16 in a manner presently described.

Formed in the square faced end portion 8 of the lever 5 for vertical alinement with the companion seats 15 in the lever 6 are holes 18 for the'engagement in any one of the same of the eccentric shank 19 of a flanging plunger 20, the shank 19 being detachably held in the hole by means of a split ring 21 detachably engaging an annular seat 22 formed in sald shank 19 and also engaged in a counter seat 23 concentrically of the hole 18 in the lever 5. The plunger 20 is formed with the tapered flanging tip 24 to telescope within the tubing end 16 when clamped by the jaws 10 and 11 on the swinging of the levers 5 and 6 together thereby outwardly flanging the tubing 16 as will be clearly apparent.

It is of course understood that different sizes of plungers 20 can be substituted one for the other for varying the extent of the flanges of thetubing end 16 as the occasion may require, the plungers 20 being detachable from the lever 5 for this purpose.

The eccentric mounting of the plungers 20 in the lever 5 permit the self adjustment of the plungers 20 relative to the tube end 16 when clamped between the jaws 10 and 11, so that the flanging tip 24 of the plunger 20 will properly aline with the tube end 16 for the flanging thereof.

It will be obvious that the tubing 16 at its end can be readily clamped in the lever 6 for the flanging of the end by the plunger 20 when the implement or pliers are in use.

From the foregoing it is thought that the construction and manner of operation and use of the pliers or implement will-be clearly understood and therefore a more extended explanation has been omitted.

What is claimed is:

1. In a flanging implement, a pair of levers, a tube end clamp on one of said levers, means swingingly connecting the levers-together, a movable member connected with the firstnamed means, and a self-adjustable flanging element detachably mounted .in the movable means.

2. In an implement of the character described, a pair of pivotally connected levers, a tube clamp on one of the levers, and a flanging plunger eccentrically and detachably mounted in the other lever for the self adjustment of said plunger relative to the tubing to be flanged when engaged in the clamp.

3. In an implement of the character described, a pair of levers, means on one of said levers for detachably clamping a tubing thereto, means for swingingly connecting the levers together, and a flanging plunger having an eccentric shank rotatably and detachably mounted in the other lever.

4. In an lmplement of the character described, a pair of levers, means on one of saidlevers for detachably clamping a tubing thereto, means for swingingly connecting the levers together, and a flanging plunger having an eccentric shank rotatably and detachably mounted in the other lever, and means for rotatably and detachably securing the eccentric shank in said last named lever.

5. The combination with a tube clamp, of a swinging member movable toward and away from the tube when engaged in the clamp, and a flanging element mounted for self-adjustment in said movable member and detachable therefrom.

In testimony whereof I hereunto afiix my signature.

JOHN F. WALTERS.
